AUTOMOBILE TILTING DEVICE. H 3

Application filed April 2,

Z all whom it may concern Be it known that I, JAMES H. NEsBrr'r, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Automobile Tilting Devices, of which the following is a specification.

This invention relates to automobile cradles 01- devices for tilting an automobile so that the underside or running gear thereof will be readily accessible for repair or other purposes, the construction being such that when the car is tilted, a mechanic can work thereon in a standing position.

The object is to provide an improved device of the kind which will be quick-acting and which will occupy little space.

In the accompanying drawings, Fig. 1 is a side elevation of the cradle. F ig. 2 is a plan. Fig. 3 is a section on the line 3-3 of Fig. 2, with the parts in one position. Fig. 4 is a view similar to Fig. 3 with the parts in another position.

A tilting frame is formed by means of rails or tracks 1, which may be channel iron, bolted to channel iron or other cross sills 2 and 3, the former being indicated at each end and the latter at the middle. Flanged rollers 4 are fastened to the Lmdersides of the sills 2, at the outer end thereof, and these rollers travel on cross rails 5 located under the sills 2. Blocks 6 are fastened to the underside of the sills 2 near the inner end thereof, and these blocks 6 rest on the rails 5 when the tilting frame is in horizontal position, as shown in Fig. 3.

Angle brackets 7 are fastened to the inner ends of the sills 2 and these brackets carry studs 8 on which are mounted rollers 9 which are confined and ride up and down between the flanges of the vertical channels or posts 10 which are fastened at their lower ends to the floor or support, and the upper ends of which may be braced by any suitable means, such as rods 11 connected to the posts and to an adjacent wall or the like.

Beside or opposite the inner end of the middle sill 3 are a pair of upright posts 12 braced by rods 13, and between the upper ends of these posts is mounted a guide pulley 14: on a shaft 15. A winding drum 16 is mounted between brackets 17 on the posts, and back slip of the drum is controlled by a ratchet l8 and pawl 19. A cable 20 is con- 1923. Serial No. 629,421.

nected to the drum and extends over the pulley 1 1 to connection at 21 to the end of sill 3. A drum 22 similar to the drum 16 is mounted in brackets 23 near the bottom of the posts 12 and is connected to a cable 24 which passes around guide pulleys 25 attached to the floor and is connected at 26 to the outer end of the sill 3.

In operation, the tilting frame is let down to horizontal position as shown in Fig. 3 and the automobile is driven onto the rails 1 and fastened thereto in any suitable manner. he frame is then tilted as shown in Fig. 1 by operating the winding drum 16 by means of its crank handle 17 The rollers 4 travel along the rails 5, and the rollers 9 travel upwardly in the guides 10. This tilts the frame and car to such position that the under part of the car will be easily accessible to the mechanic. By releasing the pawl 19 the tilting frame can be lowered to the. origi nal or horizontal position; or, if the car has been tilted to such an extent that the frame will not drop by gravity, the drum 22 can be operated to pull the lower end of the frame outwardly and so lower the frame to horizontal position. Obviously, a reducin gearing can be applied to the drums if found necessary to handle heavy cars or trucks.

1 claim:

1. The combination with a cradle comprising cross rails, upright guides at one end thereof, a tilting frame having rollers at its outer side which travel on the rails, and rollers at its inner side which travel in guides, of hoisting and lowering means connected respectively to the inner and outer sidesof the frame, and operating devices therefor mounted upon an upright support adjacent the guides, both of said operating devices being located at the same side of the frame.

2. The combination stated in claim 1, said hoisting and lowering means including ropes and pulleys connecting the inner and outer sides of the tilting frame to a hoisting drum and a lowering drum, said drums being mounted adjacent each other on said up right support.

In testimony whereof, I affix my signature in presence of two witnesses.
